# interpret

|
> A dictionary of file extensions and associated module loaders.
|
|
|
|
[](https://nodei.co/npm/interpret/)
|
|
|
|
## What is it
|
|
This is used by [Liftoff](http://github.com/tkellen/node-liftoff) to automatically require dependencies for configuration files, and by [rechoir](http://github.com/tkellen/node-rechoir) for registering module loaders.
|
|
|
|
## API
|
|
|
|
### extensions
|
|
Map file types to modules which provide a [require.extensions] loader.
|
|
|
|
```js
|
|
{
|
|
'.babel.js': [
|
|
{
|
|
module: '@babel/register',
|
|
register: function (module) {
|
|
module({
|
|
// register on .js extension due to https://github.com/joyent/node/blob/v0.12.0/lib/module.js#L353
|
|
// which only captures the final extension (.babel.js -> .js)
|
|
extensions: '.js'
|
|
});
|
|
}
|
|
},
|
|
{
|
|
module: 'babel-register',
|
|
register: function (module) {
|
|
module({
|
|
// register on .js extension due to https://github.com/joyent/node/blob/v0.12.0/lib/module.js#L353
|
|
// which only captures the final extension (.babel.js -> .js)
|
|
extensions: '.js'
|
|
});

### jsVariants
|
|
Same as above, but only include the extensions which are javascript variants.
|
|
|
|
## How to use it
|
|
|
|
Consumers should use the exported `extensions` or `jsVariants` object to determine which module should be loaded for a given extension. If a matching extension is found, consumers should do the following:
|
|
|
|
1. If the value is null, do nothing.
|
|
|
|
2. If the value is a string, try to require it.
|
|
|
|
3. If the value is an object, try to require the `module` property. If successful, the `register` property (a function) should be called with the module passed as the first argument.
|
|
|
|
4. If the value is an array, iterate over it, attempting step #2 or #3 until one of the attempts does not throw.
